5 System Connection Overview The PPA T45 is an FM Wide-Band transmitter operating in the MHz bandwidth. Three models are available - a standalone FM Transmitter (PPA T45), one with Ethernet control (PPA T45 NET) and one with Ethernet control and a Dante Input (PPA T45 NET D). Ethernet control allows the transmitter settings to be changed over a network with hard-wired or wireless devices. The Dante Input allows audio from networked Dante devices to be played through the transmitter. Compatible Williams Sound receivers include the PPA R38, PPA R37 and PPA R37-8 body pack receivers. Developed for hearing assistance in places of public access, the PPA T45 models are designed for those who need help overcoming background noise, reverberation, or distance from the sound source. They include a complete audio processor optimized for the needs of hearing impaired people and are easily integrated with an existing sound system, or used with a microphone as a stand-alone system. The PPA T45 transmitter models operate as a small FM radio station. The transmitter takes audio directly from one of it's inputs (audio sources like a microphone, sound system, mixer board, or Dante device) and broadcasts the audio on an FM channel. FM radios can be worn by listeners to hear the audio. The broadcast can be received up to 1000 ft* from the transmitter. Listeners can sit anywhere in the broadcast area and listen to the audio at the volume level they need without disturbing others. *Range is dependent on the environment.

The PPA T45 NET has an Ethernet jack but no Dante jack. The PPA T45 does not have Ethernet or Dante jacks. Power Supply Connection Connect the TFP 048 power supply to the Power Supply Jack located on the rear of the PPA T45 transmitter. Ethernet and Dante RJ-45 Connection If connecting to a network or directly to a PC, a shielded Cat 5e cable must be used. In some cases, (like older PCs) a crossover cable may need to be used. Note that "shielded" means there is a foil layer between the twisted-pair conductors and the insulation jacket. Audio Source Connections The T45 transmitter will accept the following audio sources: 1. Balanced Microphone on a 3-pin (XLR) connector without phantom power. 2. Balanced Microphone with 12 volt phantom power (DIN 45596) on a 3-pin (XLR) connector. 3. Balanced/Unbalanced microphone with or without phantom power on 1/4 inch (TRS) jack 4. Balanced/Unbalanced Line on a 3-pin (XLR) connector. 5. Balanced/Unbalanced Line on 1/4 inch (TRS) jack. 6. Digital Audio (AES/EBU) on a 3-pin (XLR) connector. 7. Digital Audio (S/PDIF) on an RCA jack. 8. Dante on an RJ-45 jack (PPA T45 NET D only). WARNING: The T45 is not designed to accept 70 volt speaker signals! This may result in damage to your system. The sound source should come directly from the system mixer or digital source as a low-level or unprocessed signal. IMPORTANT: When a suitable audio source has been determined, you MUST configure the audio source in the menu of the T45 before plugging that source in. NOTE: FCC regulations, section 15.21, requires the user to comply with the rules of transmitter operation. Any changes or modifications made by the user not expressly approved for compliance may result in the loss of all privileges and authority to operate the equipment. 6

Additional channels can be accommodated by adding a resistor for each source. Necessary resistors can be obtained from Williams Sound (Part Number RFC 472) or from any local electronics parts supplier. Note: The Dante audio input on the PPA T45 NET D will automatically mix the left and right channels. Selecting an Audio source Appropriate for Hearing Impaired Listeners If the T45 is going to be used specifically for the accommodation of hearing impaired listeners, we recommend following these general guidelines: The PPA T45 transmits audio with excellent fidelity. Therefore, the audio source signal should be of the highest audio quality and not subject to a compressor, limiter, reverberation, or other signal processing equipment. The T45 has a very effective DSP audio processor. If compression is desired in the audio, refer to the Compression section under Audio Settings - 1c. Audio Presets for available settings. Excessive compression is not helpful to the hearing impaired and can contribute to excessive noise in the receiver outputs. The T45 audio source signal is usually connected to a mixer s line output signal which is behind the mixer s parametric equalizers but ahead of any equalization used for house loudspeakers. If audio delay is available for use in large auditoriums, it s usually best to use it. Because radio signals travel faster than sound, delaying the transmitted audio so that an average listener (in the middle of the listening area) hears the transmitted audio a few milliseconds after audio from the main sound reinforcement system speaker is helpful. This will also help audience members who lip read. 7

8 phantom Personal PA DSP FM Wideband Transmitter Avoiding Hum in the Audio (as a Result of a Ground Loop) A hum created by a ground loop can often be eliminated by connecting a capacitor in series with the audio line shield to the transmitter s ground. This method also maintains good RF shielding. Determining the effectiveness of this method for your installation usually requires some experimentation. Necessary capacitors can be obtained from Williams Sound or from any electronic parts supplier.

For rack mounting, consider installing a remote antenna like the ANT 005 or ANT these antennas require using the Remote Antenna Coaxial Jack (above) and a long length of terminated coaxial cable. Another option is to mount the antenna on the rack itself - consider the ANT 029 which includes a 1RU bracket and a 3ft terminated coaxial cable. For a full list of antenna options, please go to our website and view the Antenna Application Guide under Products - Accessories - Antennas. 8

9 Connecting the T45 to other Devices The Analog LINE/MIC Input (XLR / 1/4") jack can be used with standard pro audio electronics such as standard pro audio line level, condenser microphones up to 15v or an analog line output from a mixer. The combination jack accepts either XLR or 1/4 (TRS). This source must be configured in the menu before plugging the source into the jack. The Analog Audio Line Output (RCA) jack can be used for monitoring, recording, or routing processed audio to another sound system. The AES/EBU Digital Line Input (XLR) can be used with the output of a digital mixer or digital audio source. The processors inside the T45 convert the digital bitstream into usable audio. The S/PDIF Digital Line Input (RCA) jack can be used with a device that has an RCA Digital Audio Out (also referred to as Coaxial Digital Audio from consumer electronic devices. The processors inside the T45 convert the digital bitstream into usable audio. The Remote Antenna Connection can be used to connect a remote antenna to the T45 when the whip antenna won t be used (as in the case of rack-mounting). See the Williams Sound Antenna Guide for a full range of antenna and mounting options. The Ethernet and Dante RJ-45 jacks can be used to connect the T45NET to either (1) a local network or (2) directly to a single computer or Dante device. In all cases a shielded Cat5e ethernet cable must be used. When connecting a device directly, a crossover cable may need to be used depending on the device being connected. Some older PC's require a crossover cable. DEVICE OR MIXER WITH S/PDIF OUTPUT DANTE NETWORK (SWITCH) DANTE AUDIO AND NETWORK CONTROL CAN BE COMBINED ON THE SAME NETWORK IF DESIRED (NOT SHOWN).

Listen with an FM receiver (see compatible Williams Sound receivers towards the back of this manual). Install the batteries, plug in the earphone, turn on the receiver, choose the correct channel and walk around the listening area. The signal should be clear and quite loud when the volume is turned up. 13. (T45NET and T45 NET D) Connect a shielded CAT5e Ethernet cable from your local area network, wi-fi router, or PC to the connector on the transmitter labelled Ethernet. 14. (T45 NET D only) Connect a shielded CAT5e Ethernet cable from the Dante network to the connector labelled "Dante" on the transmitter. Note: Dante IP Address and other settings are configured externally through Dante Controller; there are no settings in the transmitter for Dante, other than choosing Dante as the input source). 15. (T45 NET and T45 NET D) Once the transmitter detects an active network is present (either ethernet or Dante), the X will disappear from the Network/Dante icon on the main info screen, indicating that it has connected to the network. The main info screen will display the text ENET:\, where the last character \ will spin, while the T45 is acquiring a DHCP address. Once acquired, (usually takes less than a minute), the T45 s ethernet control IP address will be displayed in the Add-on module part of the Main Info Screen. 16. (T45 NET and T45 NET D) Open a web browser (i.e. Internet Explorer, Mozilla Firefox, Google Chrome, Safari, etc.) on a computer or mobile device that is also connected to the same local network as the T (T45 NET and T45 NET D) In the address bar of the browser, type in the IP address that is shown on the front of the transmitter's main info screen, and push the enter key on the keyboard.

The transmitter will accept the following audio sources: Balanced Microphone on a 3-pin (XLR) connector without phantom power. Balanced Microphone on a 3-pin (XLR) connector with 12 volt phantom power. Balanced/Unbalanced microphone on 1/4 inch (TRS) jack without phantom power. Balanced/Unbalanced microphone on 1/4 inch (TRS) jack with 12 volt phantom power. Balanced/Unbalanced Line on a 3-pin (XLR) connector. Balanced/Unbalanced Line on 1/4 inch (TRS) jack. Digital Audio (AES/EBU) on a 3-pin (XLR) connector (44.1 or 48 KHz sample rate). Digital Audio (S/PDIF) on an RCA jack (44.1 or 48 KHz sample rate). Dante audio The Audio Source menu has five possible selections to choose from: Analog Line In, Mic, Phantom Mic +12V, Digital AES/EBU, or Digital S/PDIF. 1b. Audio Input Gain The Audio Input Gain adjusts the incoming audio level into the T45. This adjustment affects analog and digital audio. Changes to the input level will affect the level indicated by the front panel LED s when audio is present. Audio Input Gain is adjustable from 0 db to -50 db in 1 db steps. 1c. Audio Presets The Audio Presets allow the user to quickly and easily configure the T45 for common applications. In some cases, the Audio Presets may be the only setup needed for properly configuring the T45 transmitter. There are three pre-configured and one custom Audio Preset to choose from: Hearing Assist, Music, Voice and Custom. When one of these selections is made, the performance of the T45 is immediately optimized for the needs of that application (an adjustment is automatically made to the Low-Pass Filter, High Pass Filter, and Compression). Refer to the chart below for a comparison of the Audio Preset configurations. Audio Preset Configuration Table RF Output = Full Power Preset High Pass Low Pass Compression Voice 125 Hz 6.3 khz 1:1 Music 31 Hz 16 khz 1:1 Hearing Assist 500 Hz 8.0 khz 2:1 IMPORTANT: Listen to the transmitted audio through the headphone jack, especially when deciding on an appropriate high pass filter. This is a good way to ensure the listening audience will receive the highest audio quality. By default, the T45 is shipped in the Music mode. For music, concerts, and other applications where the highest audio quality is desirable, Music is the recommended mode of operation. For hearing assistance applications, or applications where the message is critical for listening, Hearing Assist is the recommended mode of operation. For speaking and other voice applications, Voice is the preferred mode of operation. 16

17 Custom Audio Preset If the three preset configurations do not meet the needs of the venue, the Custom audio preset can be used. The custom preset allows the user to adjust the High-Pass Filter cutoff frequency, Low-Pass Filter cutoff frequency, and choose the Compression Ratio. If the audio preset is changed from Custom to Music, Hearing Assist, or Voice, the Custom settings are overwritten. High Pass Filter A High Pass Filter cuts off low frequencies and lets high frequencies pass through. The pole frequency chosen is the point where the cutoff takes effect. The high pass filter will help to remove low frequency noise from the transmitted audio signal, such as room noise, a line hum, or breath accents picked up from an improperly installed microphone. Available pole frequencies are: 31, 63, 80, 100, 125, 160, 200, 250, 315, 400, 500, and 630 Hz. Low Pass Filter A Low Pass Filter cuts off high frequencies and lets low frequencies pass through. The pole frequency chosen is the point where the cutoff takes effect. The low pass filter will help to remove high frequency noise from the transmitted audio signal, such as hiss in the audio line as a result of room noise, sharp speech sounds, or other uncomfortable high frequency sounds. Available pole frequencies are: 3.5, 4.0, 5.0, 6.3, 8.0, 10.0, 12.5, and 16 khz. Compression Compression reduces the dynamic range of the audio (volume difference between loud and soft sounds). It is typically used for voice and hearing assistance applications - for a listener who has difficulty hearing the quiet sounds of an audio broadcast, compression boosts the quiet sounds to louder listening levels. For listening to music programs, concerts, etc., lower compression ratios or no compression is generally used. The T45 has three selectable modes of compression: 1:1 (compression off), 1.5:1 (low compression) or 2:1 (high compression). For applications such as music and voice, where high audio quality is desirable, 1:1 is the recommended mode of operation. For hearing assistance or applications where the transmitted message is critical for listening, 1.5:1 or 2:1 is recommended. NOTE: The T45 is shipped from the factory at a 1:1 compression ratio (no compression). NOTE: The manager of the T45 needs to take care in using compression, because some hearing impaired people cannot tolerate as loud of a sound as those with normal hearing. Once a setting is selected, no additional action is necessary. If no buttons are pressed, after 5 minutes the OLED will return to the Main Info Screen, then after another 10 minutes show a screen saver, then go blank (the time between the screen saver and blank screen is adjustable). When the display is blank, and the RF indicator is lit, the transmitter is broadcasting. If audio is present the audio input level LED s will pulse with the level of the audio. 1d. Headphone Source The Headphone Source setting allows either input audio or transmitted audio to be monitored through the headphone jack. 1e. Headphone Volume The headphone volume level can be increased or decreased by using the Headphone Volume setting in the menu. 17

18 2. RF SETTINGS The RF Settings provide the ability to change the broadcasting Channel, RF Output Power level, and the RF time-out delay. 2a. Channel (or Frequency) The Channel setting allows the channel number or corresponding frequency to be selected. Note: this depends on what display mode the transmitter is in (see Step 3a). If the transmitter is in channel display mode, channels 1-17 or 1-8 can be selected depending on channel mode. If the transmitter is in frequency display mode, frequencies can be selected from 72.1 MHz to 75.9 MHz. Note: The T45 is shipped from the factory with the frequency pre-set to Channel 1 (72.1 MHz). Channel/Frequency Selection Chart Ch Freq (MHz) Groups can operate simultaneously without interfering with each other. The first 8 channels, highlighted in gray, have been designed for non-interference, and can be used for this purpose. Although these 8 channels have been designed to not interfere with each other, outside sources of RF interference may limit how many of these channels may be used. 2b. RF Output Power The T45 has three selectable transmitter power levels: FULL, MEDIUM (-10dB), LOW (-20 db), and RF OFF. By default the T45 is set to FULL power mode. For general listening applications, FULL power is the preferred mode of operation. Full power provides the T45 with an operating range of up to 1000 ft (dependent on the environment). For special listening applications, it may be desirable to reduce the overall operating range on the T45 if: 1) The audio transmission is to be contained to a smaller listening area; 2) The signal is too strong and it is overloading the receiver; or 3) Multiple T45 transmitters are used in adjacent classrooms where the FM signals overlap each other. In these cases, the power level on the T45 can be reduced to -10 db or -20 db. The RF output may be temporarily set to OFF (no power) to help troubleshoot interfering or overlapping RF signals. 2c. RF Time-Out The RF Time-Out setting determines how long the transmitter continues to transmit with no audio present (30 minutes, 4 hours, or Always On). Note that the RF Time-out delay and Screen Time-out delay are two independent events. After the RF time-out period occurs (with no audio input and no front panel button presses), the T45 will go into sleep mode to conserve power. During sleep mode the RF transmitter is completely shut off and the power switch light will fade from bright to dark to indicate the unit is in sleep mode. REMINDER: If the lock icon is displayed on the default display, the menu screens are locked, and you will not be able to make changes from the front panel. To unlock the menu screens, refer to Lock/Unlock Settings under Controls and Features. 18

19 3. PREFERENCES The Preferences Settings provide the ability to change the Display Mode, Channel Mode, Screen Time-Out, User-Entered Transmitter Description, or Restore Factory Default Settings. 3a. Display Mode The Display Mode setting determines (1) whether the channel or frequency is larger on the front display of the transmitter and (2) whether frequency or channel is displayed as the adjustment under the RF CHANNEL setting (see step 2a). 3b. Channel Mode The Channel Mode changes the range of selectable channels from all 17 channels to the 8 non-interfering channels. This comes into play when multiple transmitters are in use, serving multiple groups of listeners. 8-Channel mode allows the user to choose one of the 8 non-interfering channels for simultaneous transmission from multiple transmitters (i.e. Transmitter #1 on Channel 1, Transmitter #2 on Ch. 2, Transmitter #3 on Ch. 3, etc.) and prevents channels that would interfere from being available. 3c. Screen Time-Out The Screen Time-Out setting determines how long the transmitter displays the screen saver. The transmitter waits for 10 minutes, after no activity (front panel button pushes), then displays the screen saver. After displaying the screen saver for the period of time set here, the transmitter display will shut off to conserve energy. Note that the Screen Time-out delay and RF Time-out delay are two independent events. 3d. User-Entered Transmitter Description The Description field allows the user to easily identify the transmitter. This typically comes into play when multiple transmitters are being used - to be able to distinguish one from another. The description appears on the front main info screen, and also on the web page (PPA T45 NET and T45 NET D). In a rack, all the user has to do is activate the main info screen with a touch of any button on the front, and the description is displayed as one of the fields on the main info screen. On the web interface (PPA T45 NET and T45 NET D), the description appears on the Home page, making it easy to identify which transmitter the web page is controlling. Note that the default description YOUR T45 NAME HERE will appear if it has not changed. It s also possible to enter all blanks in the description field, and then the description will be blank on the front display. 3e. Restore Defaults The Restore Defaults action will restore the transmitter to it s original factory settings. This includes the Audio Preset, Input Source, Input Level, Headphone Source, RF Channel/Freq, RF Output Power, RF Time-Out, Display Mode, Channel Mode, Screen Time-Out, and Description. If the optional Ethernet Module is installed, it will also reset the IP address, Subnet Mask, IP Address Mode, and Web Page Security Password. Note: Restoring defaults from the front panel will restore (reset) all settings. Restoring defaults from the web page will restore (reset) all settings except NET and Dante connectivity settings (IP Address, Subnet Mask, IP Address Mode, and Web Password). This maintains connectivity between the Web Page and the T45 (NET and NET D) as well as the Dante source (NET D), after the T45 reboots. 19

20 4. ADD-ON MODULES (PPA T45 NET and PPA T45 NET D) The Add-On Module Settings show up in the menu only if the optional ethernet module is installed (PPA T45 NET) and Dante module is installed (PPA T45 NET D). This menu provides the ability to view the Status of the add-on modules, choose the IP Address Mode (Static or and Dynamic IP Addressing), change the IP Address and Subnet Mask, set/change the Security Password and choose whether or not to display the IP Address on the front display. 4a. Network Status The Network Status screens show which module is installed (Network Control Module, Dante Module) and reports status of these modules. There are 4 info screens. Module(s) Installed LINK ESTABLISHED, ACQUIRING or NOT CONNECTED DHCP or STATIC Addressing Name assigned in Dante Controller Name stored on unit LINK ESTABLISHED, ACQUIRING or NOT CONNECTED These will either be populated or NOT CONNECTED. An asterisk * means that the device has disconnected from the network since the last network update and the device is using the last assigned IP Address. When the * disappears, the network has updated the IP address. This may be used ot diagnose an intermittent network connection or cable. Sample rate of Dante Module audio Dante module MAC address Note: An asterisk "*" after IP Address, Subnet Mask, or Gateway means that the network connection has been broken, and the transmitter is continuing to use the existing IP Address, Subnet Mask, or Gateway until the network connection is restored. 4b. Network Settings The Network Settings screen where the IP Address Mode (Static or DHCP), the IP Address, and Subnet Mask are set. IP Address Mode Static or DHCP IP Address If the IP Address Mode is set to Static, this is where the IP Address is manually entered Subnet Mask If the IP Address Mode is set to Static, this is where the Subnet Mask is manually entered 4c. Ethernet Admin The Ethernet Admin screen is where the web page login Password is set/reset (the User Name is fixed to admin ), and displaying or not displaying the IP Address on the front of the T45 can be set. Network Log-in Allows the network password to be reset. IP Address Display Choose whether or not to show the ethernet control IP Address on the front display screen. 20

21 Network Setup for Hard-wired devices (Laptop or Desktop PCs) The PPA T45 NET and NET D provide a web interface (set of web pages) to manage the transmitter settings. These web pages can be accessed over an Ethernet network, either hard-wired (through a laptop or desktop PC) or wireless (through an ipad, Android tablet, or smart phone). The web pages can be accessed with nearly all internet browsers, like any website. Nearly all of the settings that can be changed on the transmitter can be accessed and changed through the front panel controls - or the web pages. Note that the web pages have a different look and feel than the front panel menu tree, but nearly all of the same settings can be accessed (not on web page: Screen Time-out, Headphone Source, Headphone Volume). 1. It is assumed that the network has already been set up, and a laptop or desktop pc is connected on the network. 2. Determine an appropriate static IP address for the T45. If using dynamic IP Addressing, skip to step 4. a. If someone set up your network, they may be able to help you determine an appropriate IP address (i.e. network system administrator). b. There should be no other device having this same address on the network. c. This will be an address on the same subnet as the router. d. For example, if the router s address is , the first three sets of numbers will be the same (i.e ), and the last number will be the number you determine for the T45 (i.e..100), making the IP address for the T When you determine this address, remember or write it down. You will need it for a later step. 3. Set the Static IP Address for the T45 by using the controls on the front of the T45. a. Enter the IP Address you determined in step 2. (When entering/saving the new address, the T45 will automatically change its IP Address Mode to STATIC) b. All settings in the T45 take place immediately (they change when saved). 4. Plug the network cable into the T Connect to the T45 with the Laptop or Desktop PC. If using a Static IP Address: a. Open the web browser on the Laptop or Desktop PC. b. In the address bar of the browser, type in the address of the T45 (from step 2) and hit Enter. c. You should see the Log In Page of the T45. d. Log In using the default user name admin and password admin. If using DHCP (Dynamic IP Addressing): When using DHCP addressing, the IP Address can be viewed on the front panel of the T45NET. However, when doing remote installation, there is an optional discovery utility program available on our website called the Williams Sound Device Discoverer Tool. This tool allows the discovery of T45NET devices on a local network and shows their IP Address. a. Once downloaded and installed, open the Williams Sound Device Discoverer.jar Tool on the Laptop or Desktop PC. (If the tool doesn t open you may need to update the PC to the latest version of Java). All T45 NET and NET D unit(s) should show up with it s (their) ethernet control IP Address(es). Write the IP Address down, you ll need it for a later step. Williams Sound Device Discoverer Tool (optional) 21

22 b. Open a web browser on the Laptop or Desktop PC. c. In the address bar, type in the IP address of the T45 (static from step 2 or dynamic from step 5) and hit Enter. d. When you connect to the T45, you should see the Login Page. 6. After logging in, verify control of the T45 by changing a setting from the web page, and watching it change on the T45 front panel display. a. An easy setting to verify is changing the channel. 7. For easy access next time, build a favorite link to the T45 (just like you would for a favorite website). a. If you can t make a link, you can always go back to the IP address (step 5) by going into the website history or typing in the first few numbers of the address (i.e ) into the address bar and it should see the link you recently visited. This method is cumbersome, which is why a favorite link is suggested. Note: The procedure outlined here is a simple example of the basic steps required to set up control of the T45 transmitter with a hard-wired computer. Existing network topology, security, type of devices and network preferences all contribute to how the network may be set up and how you may be able access the T45. Consult with a trained IT professional if you are unsure how you should set up network control. Network Setup for Wireless Devices (ipad, Android Tablet, or smart phone) The PPA T45 NET and NET D provide a web interface (set of web pages) to manage the transmitter settings. These web pages can be accessed over an Ethernet network, either hard-wired (through a laptop or desktop PC) or wireless (through an ipad, Android tablet, or smart phone). The web pages can be accessed with nearly all internet browsers, like any website. Nearly all of the settings that can be changed on the transmitter can be accessed and changed through the front panel controls - or the web pages. Note that the web pages have a different look and feel than the front panel menu tree, but nearly all of the same settings can be accessed (not on web page: Screen Time-out, Headphone Source, Headphone Volume). 1. Get the Router IP address, Router SSID (Wi-Fi broadcasted name) and Router Wi-Fi Password. a. If someone set up your network, you will need to get this information from them (i.e. network system administrator). Remember or write them down. You will need these for later steps. 2. Determine an appropriate static IP address for the T45. If using dynamic IP Addressing (DHCP), skip to step 4. a. If someone set up your network, they may be able to help you determine an appropriate IP address. b. There should be no other device having this same address on the network. c.

Plug the network cable into the T45. If using a Static IP Address, skip to step 6. 22

23 5. Find the Dynamic (DHCP) IP Address of the T45, either from the front panel, or remotely with a Laptop or Desktop PC. When using DHCP addressing, the IP Address can be viewed on the front panel of the T45NET. However, when doing remote installation, there is an optional discovery utility program available on our website called the Williams Sound Device Discoverer Tool. This tool allows the discovery of T45NET devices on a local network and shows their IP Address. Once downloaded and installed, open the Williams Sound Device Discoverer.jar Tool on the Laptop or Desktop PC. (If the tool doesn t open you may need to update the PC to the latest version of Java). The T45(s) should show up with its (their) IP Address. Write the IP Address down, you ll need it for a later step. Williams Sound Device Discoverer Tool 6.

Consult with a trained IT professional if you are unsure how you should set up network control. 23

24 Web Control Interface The PPA T45NET provides a web interface (set of web pages) to manage the transmitter settings. These web pages can be accessed over an Ethernet network, either hard-wired or wireless, with most internet browsers. Transmitter settings can be accessed and changed through the front panel controls - and/or this web interface. Some changes take place live, while others take effect when applied or saved. Any updates made through the front panel will show up on the web interface, and vice-versa. Main Login Page and Ethernet Communication Status The Password is stored inside the T45. The User name is admin and the default password is admin. The user name is not changeable but the password can (and should) be changed (on the web Admin page). Log-In Screen (First screen when connecting to IP Address) Click on Log In to bring up the authentication window Authentication Window User Name: admin Default Password: admin Once logged in, this RED message bar will appear until the default password is changed. This message can be turned off (suppressed) for this browsing session only. Note that this will suppress all message bars for the remainder of this browsing session only. This green dot BLINKS to indicate the browser is COMMUNICATING with the T45. When the dot is SOLID GREEN the browser is ATTEMPTING TO CONNECT to the T45. OTHER COLORS indicate possible ethernet CONNECTION ISSUES between T45 and LAN. 24

25 Home Page and Event Log The Home Page shows a summary of the T45 status; there are no controls on this page. The Event Log is only active during each browsing session. When the browser is closed, the log is cleared. When the browser is re-opened, a new event logging session begins. Very important: The log is designed for secondary PC viewing. The primary PC is the one using the web interface to control the T45. It's changes (events) are being logged by the secondary PC. Although some events may show up in the primary PC's log, the secondary PC is the machine used for recording and logging events. For example, a facility may have a dedicated server PC in a locked IT room used for monitoring events on the network. This "secondary" machine would have a T45 browser window open and capture the events of the T45. When the primary PC on the network makes changes, that machine may not have complete visibility into the entire log. The secondary PC gives an IT person visibility into what is happening with the T45 if remote changes (on the primary PC) have been made. Click on the Model Number to display the Event Log* Transmitter Model (not user-changeable) Transmitter Description (changeable through web interface and front panel) Front Panel Display (live) Self Tests pass only if browser is communicating with the T45 RF Power Level and Status Log Out Button appears on all pages Link to online User Manual *Event Log (Click on model number on the top right to display -or- also available on the Admin page) 25

26 Audio Settings Page The Audio Settings page displays all current audio settings, as well as corresponding T45 web-based controls. Note: Turning off the Audio Level Monitor may improve performance of the webpage, particularly on mobile devices that have less processing power. Network speed can also affect the audio monitor updating and web page performance. Click on this small rectangular button to start/stop the Audio Level Monitor Audio Level Monitor (update speed may vary, and may be delayed when compared with the front panel LEDs) Audio Input Gain Adjust (goal is to have audio peaking around 0dB) Audio Input Select (includes Tone Generator as a selection, for testing) Audio Configuration Presets (numbers will change but will be shaded out below for Voice, Music and Hearing Assist Presets) Custom Audio Preset Configuration (becomes adjustable when Custom button is selected) Apply changes button (required for changes to take effect, but only becomes clickable if a change has been entered) 26

27 RF Settings Page The RF Settings page displays all current RF-related settings as well as corresponding T45 web-based controls. Channel or Frequency Select (depends on Display Mode selected) Transmitting Power Sets time delay for transmitter to stop transmitting if no audio is detected on input(s) and no buttons are pressed. Log Out Button available on every page Preferences Page The Prefs page displays user preferences that can be tailored to each T45 application. Changes what appears as large or small on the front display and what appears first on the web interface channel/frequency pull-down list. Selects either the 8 non-interfering simultaneous broadcast channels, or all 17 channels. Enables the custom description field for editing. Enables the T45 to use the first 20 characters of the Dante Device Name as the T45 Description. The text entered here will appear on the front panel of the T45, on the web interface, and on the Williams Sound Device Discoverer tool after the apply button is clicked. 27

28 Network Settings Page The Network Settings page displays network and Dante connectivity settings. Typically these are not needed after initial installation. Set Dynamic/Static IP Address Mode Set static IP Address and Subnet Mask. Grayed out when DHCP is selected. Click on Apply to save changes. The T45 will reboot and the web interface will reconnect at the new IP Address. Dante Info shown on PPA T45 NET D model only. Administration Page The Admin page displays administrative controls that can be used to help with non-technical T45 users, or for remote site troubleshooting purposes. Change Password here. (User Name is fixed and cannot be changed.) 2 ways to open the Event Log. Locks the Front Panel buttons, preventing unauthorized changes. (Same as front panel settings lock) Shows/Hides the IP Address on the Front Panel, providing tighter security. Reboots T45 and web interface will reconnect when finished Restores defaults except IP Address Mode, IP Address, Subnet Mask, and Password. If performing a reboot remotely, this insures that the user can reconnect after the reboot. When connected to the internet, the T45 checks for a newer version of the web browser. If available, the newer firmware can be downloaded, saved on a PC, then implemented here. Steps to upgrade web interface: The T45 and the PC must have access to the internet (not just the LAN) to perform these steps. 1. Compare the installed version with the latest version. If the latest version is a higher number, the web interface can be upgraded. 2. Click on latest version number link. 3. A download window appears on the PC. Save the BIN file. (The BIN file is also available on our website under Support - Software) 4. Using this page, browse to the BIN file and click on Upgrade. 5. The T45 will display a page confirming that the upgrade was successful. This update must be done for each T45 on the network that needs to be managed with the Web Interface. 28
